Consider this reaction, which occurs in the atmosphere and contributes to photochemical smog: P2O5(s) + 3H2O(l) →2H3PO4(aq)

If there is 15.01 g P2O5 and excess H2O present, the reaction yields 16.5 g H3PO4. Calculate the percent yield for the reaction.

the increase of protons   hope this

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
